We have changed the OO Server certificate in OO and added a new one following the steps in the following guide:
But chrome still shows the warning saying that the connection is not private.
The reason of the issue that you are facing is the browser security policies, because of support ending for Symantec SSL Certificate. So, if you open a website running under the Symantec SSL Certificate, Chrome and Firefox will treat them as insecure.
Basically Google chrome and Mozilla Firefox no longer recognizes a Symantec SSL / TLS certificate issued before the 1st of June, 2016.
As such, if the site has a certificate from Symantec providers (Rapid SSL GeoTrust, VeriSign, Thawte, Verisign, Equifax) and the certificate hasnât been updated after the 1st of June, 2016 the error will appear.
//////////////// Announcement ////////////////
This is a public announcement from browser to every website owner. browsers had already started the process of ending support for Symantec Certificate. A website that still has Symantec SSL Certificate and had not replace the certificate from April 17 2018.
NET::ERR_CERT_SYMANTEC_LEGACY, means that the site is using a legacy Symantec certificate that is no longer supported.
